Clip lines to the extent of the corridor, and select valid segment edges

Lines that intersect the river and that cross the corridor from side to side are considered valid segment edges. We group valid segment edges that cross the river in nearby locations, and select the shortest line per cluster. From these candidate segment edges, we select the ultimate set of non-intersecting lines by dropping the longest segments with most intersections.

Arguments

lines

Candidate segment edges as a simple feature geometry

corridor

The river corridor as a simple feature geometry
